Changes in psychiatric disorder incidence patterns during the COVID-19 pandemic in Korea: a study using the nationwide universal health insurance data.
Article in BMC psychiatry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFew studies have evaluated the incidence of various psychiatric disorders during the coronavirus disease (COVID-19) pandemic using hospital visit data for the entire population of a nation. We used Korea's universal compulsory health insurance data to conduct a descriptive analysis to evaluate changes in psychiatric disorder incidence during the COVID-19 pandemic.
methodsHospital visit data related to psychiatric disorders were retrieved from the National Health Insurance Database. First-ever diagnosis for specific psychiatric disorders for each Korean was identified (from January 2015 to February 2023) and monthly age-standardized incidence rates were calculated. An interrupted time-series analysis was used to estimate counterfactual disease incidence rates and observed and counterfactual rates were compared using difference-in-difference framework.
resultsCompared to pre-pandemic period, there was a decrease in the incidence [percentage changes in monthly rate (95% confidence intervals)] of organic mental disorders [-14.6% (-18.4, -10.9)] and psychoactive substance related disorders [-12.9% (-17.5, -8.3)] during the pandemic. However, anxiety disorders [8.8% (3.1, 14.6)], behavioral syndromes associated with physiological disturbances [8.1% (4.2, 11.9)], mental retardation [8.6% (3.0, 14.2)], psychological developmental disorders [19.6% (11.5, 27.7)], childhood- and adolescent-onset behavioral and emotional disorders [45.1% (28.4, 61.8)], and unspecified mental diseases [51.8% (39.8, 63.8)] increased.
conclusionsPsychological disease incidence patterns changed substantially during the pandemic in South Korea. Various pandemic-related stressors, such as disrupted lifestyles and hospital accessibility, may have influenced these changes. The causes and public health consequences of these changes require further evaluation.
